Hi Jukka,
Here is a script that leverages the JTS distance function:
{
import com.vividsolutions.jts.geom.*;
import com.vividsolutions.jump.feature.*;
import com.vividsolutions.jump.workbench.model.*;
fc =
wc.getLayerNamePanel().getSelectedLayers()[0].getFeatureCollectionWrapper();
Iterator i = fc.getFeatures().iterator();
if (i.hasNext()) {
feature = (Feature) i.next();
geoOne = feature.getGeometry();
feature = (Feature) i.next();
geoTwo= feature.getGeometry();
htmlFrame = wc.workbench.frame.outputFrame;
htmlFrame.createNewDocument();
htmlFrame.addText("Distance = "+geoOne.distance(geoTwo));
wc.workbench.frame.flash(htmlFrame);
htmlFrame.surface();
}
}
regards,
Larry
